BARREL-HOOP MACHINE.

SPECIFICATION forming part of Letters Patent No. 330,259, dated November 10, 1885.

Application filed June 18, 1885. Serial N0.169,069. (No model.)

the county of St. Groix and State of Wisconsin, have invented a new and useful Improvement in Hoop Splitting and Dressing Machines,

of which the following is a specification.

My invention relates to a machine for making hoops, in which the mechanism for split ting a hoop from the pole is mountedin the same frame with mechanism for dressing it.

Preferably two or more of these machines are mounted in the same frame, each set requiring a workman for operating them.

- The invention relates also to certain modifications in the construction of the several parts of such machines, as will be hereinafter fully described with reference to the accompanying drawings, and particularly pointed out in the claims.

Figure I is a side elevation, partly in section, of my improved hoop splitting and dress machine. Fig. II is a plan of the same. Fig. III is a front end elevation. Fig. IV is a transverse sectional splitter in side and axial section. Fig. VI is a detail view of the mechanism for holding one of the feed-rolls up against the hoop while the latter is being dressed. 1

1 may represent the frame of a machine in which are mounted two or more sets of the splitting and dressing mechanism. In the drawings I have shown two of such sets mounted in the same frame. I

2 2 are the rotary splitters, mounted in pairs, as shown, on shafts 3 3, journaled in brackets bolted to the frame, and driven by gears 4 and pulley 5 on the main shaft 6 of the splittingmachine, which latter receives motion by belt 7 from the counter-shaft. The splitters 2 may be described as formed of adisk with an equal peripheral bevel on bothsides, and provided on the outside, or the side which comes in contact with the hoop stripped from the pole, with radial ribs a, which are beveled in two planes, that from w to y being at a greater angle to the axis of the cutter than the bevel of the disk orbody of the splitter, while that from y to the periphery z is considerably less;

view on the line IV IV, Fig. II. Fig. V is a detail viewof the rotary in other words, the splitters may be de' scribed as formed of a disk beveled in a single plane on one side, and beveled on the other side in two planes,that portion of the bevel from auto 1,! being ofa greater and that portionof said bevel from y to the periphery 2 being at a less angle to the axis of the splitter than the bevel on the opposite side of the splitter. The disk thus formed is then cutwith radial Vgrooves b, the bottoms of which make an angle to the axis of the splitter equal to that of the bevel on the opposite side. These are merely two ways of minutely describing the formation of the structure, which, broadly stated, is a splitter beveled on both sides, and provided on one side with radial ribs formed in two planes. It will be observed that the V-grooves b extend to the periphery z of the disk, but no farther, so that splitter is without peripheral teeth or notches of any description.

I am aware that reaming-saws have been provided with peripheral teeth and beveled equally on both sides, and also that splitters have been beveled on one side and provided with peripheral notches; but such are not the equivalents of my invention, for the reason that the periphery of my invention is continuous without teeth or notches, and it is furthermore-provided with radial ribs formed in two planes, as already described.

It is found that such a construction will avoid the shattering or splintering of the hoop caused by a splitter having continuous bevel.

The upper bracket, 8, within which the upper shaft, 3, is journaled, is so bolted. to the frame, as shown in Fig. I, as to be capable of vertical adjustment.

In the front and to one side of the splitters or cutters 2 are arranged upon vertical shafts 9 rotary knives 10, adapted to come in contact with the round surface of the hoop before it reaches the splitters, and thus strip from it any knots thereon. Upon the shafts 9 are arranged pulleys 11, adapted to receive motion from the countershaft or from any moving part of the machine, as desired. Almost surrounding the st-ripping-knives 10 are arranged guards 12, to expose only sufficient of such knives to enable them to remove the knots too -which. arepivoted on a. sleeve, 32, bolted to- 4.2, which iscarried by slide 43, moving feed-rollers 21, together with shown inv Fig. V, by-pulley 40 fromany movin'gpantofi the..ma-. chine.

which may come in contact with them, while the guards prevent the knives from cutting into the body of the hoop. The guards 12 are fixed to standards 13, supporting the journals of vertical shafts 9, and adjustable transversely of the machine on their brackets. 14 by means of screw 15. Adjustment of the brackets and standards carried thereby longitudinally of the machine is afforded by sup.- porting the brackets on the means of dovetail guides 16, may be fixed by set-screws 17.

From the splitters the pole and the hoop split therefrom pass to the dressing-table 18,

to which they the pole passing straight over the table and" the hoop being deflected by guide 19, so as to gobetween the feed-rollers 2O 21 21. The feed-rollers 20 20 are connected by endless belt 22, against which the bark side of the hoop is pressed by plate-springs 23 23, fixed at one end to the table, as shown. Lhe sets of feed.- rollers 20 21 may be both or either positively actuated, being keyed to their spindles. 24, which bear at their lower ends pinions25, geared; directly or through the medium of connecting-gear 26 with a pinion, 27, upon vertical shaft 28, adapted to receive motion by bevelrgear 29.fro1n the main shaft 30 of the dressingmaohine. The spindles 24 oil the the spindlesof the connecting-gear which. may be employed, are mounted vertically in two frames, 31 31,

themain frame, as shown. at 33, and serving asbearing for the upper end; of the vertical shaft 28.

By mounting the feed-rollers 2121 011 movable. carriages or frames 31 31 I am. enabledzto. employ mechanism for pressing them against the hoop with any desired; force, and; for this; purpose I employ the mechanism shown in, Fig. VI, in which 34 is, a rectangular lever pivoted tothe table at 35, connected by link 36.to,the frame 31, and provided onitslonger limb with an adjustable weight, 37

The rotary knife 38 for dressing the inside ofithehoop is placedmidway betweenthetwo: sets of feed-rollers, andmounted: on vertical;

shaft 39, supported. in. the main frame, as and. adaptedv t-o bedrivem In order to press the hoop upv against the dressing-knife in a. manner to regulate its. thickness when dressed, I employ. a, supplementary roller, 41, mounted. loosely-on spindle 111$ dovetail guides. 44 on the dressingtable, ands adjustable by handscrew 45. A set-screw, 46,. in one guide enables the fixing; of the slide andthe roller at any desired position, solasto produce hoops of a constant thickness.

To the rear end of: the machine, on toplofg thetable, is journaled the transverse shaft 47,, adapted to be driven by pulley 48 from any: desired portion of the machine, and having main frame by fluted or roughened rollers 49 to receive the I pole from which the hoop has been split, and to turn it forward to a convenient position for the operator to again seize it. The shaft is for this purpose driven in a direction contrary to the feed.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
